Overall Grade Formula
The weightage assigned to each scoring item is part of a total of 100%. If a particular item has a different maximum point value, it will be converted to 100% by dividing it by the maximum score.
((Score1 / Total Points * Weight) + (Score2 / Total Points * Weight) + (Score3 / Total Points * Weight)) * Overall Weight
The weightage assigned to each scoring item is part of a total of 100%. If a particular item has a different maximum point value, it will be converted to 100% by dividing it by the maximum score.
In this type of grading system, the grade for a course might be calculated as follows:
Example:
| Item |
Points Points Possible |
| Exam 1 |
200 |
| Exam 2 |
300 |
| Assignment (Category) |
500 |
Here, grading can be weighted. Weighting can be by item or category in Blackboard.
Example of weighting by items and category (column):
| Item |
(Points Earned/Points Points Possible)*Weight |
Points Toward Final Grade |
| Exam 1 |
(150/200) * 0.25 |
0.1875 |
| Exam 2 |
(275/300) * 0.25 |
0.22916 |
| Assignments (category) |
(450/100) * 0.50 |
0.45 |
| Final Grade |
|
0.866666 x 100 = 86.66 |
